A PARTIAL LIST OF THE COCCIDiE OF OHIO. 

 By F. M. Webster and A. F. Burgess, Wooster, Ohio. 



in connection with the following list a short explanation is not 

 inappropriate. The supervision of the work of nursery and orchard 

 inspection was placed in the hands of Mr. Webster in 1900, and the 

 original intention was to gradually collect as much data as possible 

 while carrying out the work and later to publish a report that would 

 be of service to the people and at the same time contain matter of 

 value to the science of entomology. With the retirement of the board 

 of control and the resignation of Mr. Webster, as well as the placing 

 of the inspection work in the hands of the State board of agriculture, 

 the original project had to be abandoned. But we have thought that 

 the fragments obtained during this time were worth placing on record 

 and whatever of value they might possess made available to other 

 entomologists in Ohio or elsewhere. We do not present this as a com- 

 plete list of the Coccida? of Ohio, by any means, but rather as the 

 possible basis for a better one, and which will, beyond a doubt, be the 

 work of others than ourselves. 



We are greatly indebted to Mr. George W. King and Prof. T. D. A. 

 Cockerell, who made most of the determinations for us at the expense 

 of much time and labor, and without their aid we should hardly have 

 attempted the list at all. Dr. Howard and his assistants have also aided 

 in the same manner. We have also included such species as were con- 

 tained in Prof. Herbert Osborn's list, included in his "Remarks on the 

 Hemipterous fauna of Ohio with a preliminary record of species" 

 (Eighth Annual Report of the Ohio State Academy of Science, pp. 

 60-79, 1900), and also species collected by Professor Osborif > assistant, 

 Mr. J. (t. Sanders.
